Hinged Electronic Display A-Frame for Flexible Advertising Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 'A'-frame advertising boards lack adjustability, as they require repainting for content changes and have limitations with removable writing being non-waterproof and prone to smudging, or are restricted by fixed spacing and typeset.
Innovation Solution
An apparatus with hinged planar bodies featuring electronic displays, a controller for content management, an alarm system, and movement detection, allowing for flexible content updates and secure display with built-in screens and retractable wheels for activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional sign-writing is painted on the A-frame board, then the advertising content is durable and waterproof, but changing the content requires repainting the entire surface which is time-consuming and costly
Solution Approach 1:
The patent replaces physical sign-writing with electronic display screens that show digital copies of advertising content. This allows instantaneous content updates by simply changing the digital display data, eliminating the need for physical repainting while maintaining durable, waterproof display capabilities through the electronic screen technology.
Solution Approach 2:
The patent substitutes the mechanical process of painting and physical writing with an electronic control system. The controller receives digital content and displays it on the electronic screens, replacing the manual mechanical actions of painting and writing with automated electronic processes that enable rapid content changes.
2Adaptability or versatility
If chalkboard coating is applied to allow changing artwork, then content can be easily changed, but the surface is not waterproof and smudges when touched
Solution Approach 1:
The patent uses electronic display screens to present digital copies of advertising content instead of physical writing surfaces. This eliminates the need for chalkboard coatings entirely, as the electronic display provides both easy content changeability and inherent waterproof, smudge-resistant properties through its sealed electronic architecture.
Solution Approach 2:
The patent employs composite construction combining electronic display technology with waterproof housing materials. The electronic screens are integrated into a sealed structure that provides both the desired content changeability and the required waterproof and smudge-resistant reliability, eliminating the trade-off present in chalkboard solutions.
3Adaptability or versatility
If removable writing is used on the A-frame board, then content can be changed without repainting, but the writing is limited to fixed spacing and typeset options
Solution Approach 1:
The patent uses digital content storage and display to provide unlimited layout and typeset customization options. The controller can display various fonts, sizes, colors, and arrangements of text and graphics without being constrained by physical writing limitations, while the digital copying mechanism allows instant switching between different content layouts.
4Adaptability or versatility
If electronic displays are added to the A-frame board, then content update flexibility and waterproof performance are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent integrates multiple functions into the electronic display system: the screens serve as both the advertising content display and the waterproof protective surface, the controller manages content updates and alarm functions, and the movement detector provides security monitoring. This multi-functionality reduces overall system complexity compared to having separate components for each function.
